This map set compares the hydrology in both counties.
The maps are derived from a D. H. Davison map of Franklin County, published in 1858 and a Jedediah Hotchkiss map of Augusta County, published in 1870 and based on surveys completed "during the war." The maps have been georeferenced at the Virginia Center for Digital History, using ESRI Arc Info to produce a Geographic Information Systems map and database of households.
